Then you have 6 vertices. No problem.
A pentagon.
cubes, prisms, dodecahedrons...
A cube is a geometric shape which has 6 faces and 8 vertices ie .2 more vertices than faces
That could be any quadrilateral or pentagon.
Shape has fewer than 6 sides
There are many shapes that have fewer than 3 vertices like the circle, hyperbola, semi circle, and many others. However if you are only talking about polygons then there is no actual shape with fewer than 3 vertices that you can find in a real life situation but they do have names for these shapes. A 2-sided polygon is known as a digon. A 1-sided polygon is known as a monogon. These shapes only exist in theory however and not in real life.
No.

No.
They are polygons. They have fewer than 5 sides. They have fewer than 5 vertices.
No. They have more than 6.
A pentagon.
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
